Write a program that let the user input two number and displays the result as the example below:
輸入兩個數字，做加減乘除的運算
Example input 1:
5 6
Example output 1:
5+6=11
5-6=-1
5*6=30
5/6=0.833333
Example input 2:
1.23 3.45
Example output 2:
1.23+3.45=4.68
1.23-3.45=-2.22
1.23*3.45=4.2435
1.23/3.45=0.356522
Remember: Your output maybe 100% correct, but your code matters!
